[Bug 1663971] Re: Qualcomm Atheros QCA6174 802.11ac - drops out for a few seconds frequently
An update on this bug - since moving to Ubuntu 16.04.2 (which ships with 4.8), I can no longer seem to reproduce any wireless network downages. This also applies to 4.10. What I can't seem to understand, though, is why the kernel keeps wanting a file named `ath10k/QCA6174/hw3.0/firmware-5.bin` - if it can't find this file, then how am I no longer having network issues? ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663971 Title: Qualcomm Atheros QCA6174 802.11ac - drops out for a few seconds frequently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1663971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1663975] Re: XHCI errors causes dock USB and network adapter dropouts
While installing Dell-provided software and drivers for Windows, I became armed with additional information about the dock - it is a Realtek NIC connected to an ASMedia host controller. Armed with that and the search phrase "realtek ep_index 2 comp_code 13" provides the following result, which shows this problem is known not just here (find on the page posts made by Ansis Atteka ) https://groups.google.com/forum/#!msg/linux.kernel/vdR3nK8k8zM/Vhbp1CjtBgAJ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663975 Title: XHCI errors causes dock USB and network adapter dropouts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1663975/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1663975] Re: XHCI errors causes dock USB and network adapter dropouts
A colleague with the same laptop told me that Windows does not experience any wired dock network dropouts. To rule out any hardware being possibly faulty - I ran continuous network file transfers on Windows 10 for 24 hours and did not see any diminished performance, let alone any outright network failure. Installing Ubuntu 16.04.2 again (with 4.8) and testing that as well as with 4.10 makes the problem reproducible: - xhci_hcd :0e:00.0: ERROR Transfer event TRB DMA ptr not part of current TD ep_index 2 comp_code 13 - xhci_hcd :0e:00.0: Looking for event-dma [16-digit-integer] trb-start [16-digit-hexadecimal] trb-end [16-digit-hexadecimal] seg-start [16-digit-hexadecimal] seg-end [16-digit-hexadecimal] This, along with other users running into the same issue, points to the issue being _clearly_ software related unless I've missed something in my diagnosis. What other data can I provide? I wish I could be of more help, but am not competent enough to know where to even begin to write a patch. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663975 Title: XHCI errors causes dock USB and network adapter dropouts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1663975/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1663975] Re: XHCI errors causes dock USB and network adapter dropouts
Hi - sorry for the delay in response. I wanted to wait until the final 4.10 was released, and then had some prior obligations I had to tend to until now. I and colleagues with the same machine (which rules out a hardware problem) experienced this problem out of the box with 16.04.1 (which provides 4.4). While on 16.04.1, I tested with 4.4, 4.9 and 4.10 (rc8), and on 16.04.2, I tested with 4.8 and 4.10 (final). All tested kernels have me run into the exact same xhci_hcd error about `TRB DMA ptr`. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663975 Title: XHCI errors causes dock USB and network adapter dropouts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1663975/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I have submitted this bug on 4.4 as recommended by a colleague, but the issue continued to persist in 4.9 and 4.10 in the same manner and dmesg emitted the same messages I point out here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663971 Title: Qualcomm Atheros QCA6174 802.11ac - drops out for a few seconds frequently To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1663971/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1663975] Re: XHCI errors causes dock USB and network adapter dropouts
The same xhci error happens in 4.9 and 4.10 which causes the network adapter to fail or cause usb devices to drop out, needing re-plugging in, in a manner exactly like here for 4.4. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663975 Title: XHCI errors causes dock USB and network adapter dropouts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1663975/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
